Specification of Letters Patent.

Application filed November 25, 1512.

Patented Sept. 23,1913.

Serial No. 733,457.

To all whom it may concern:

Be it known that I, Fnnns B. KLnINTon, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Tables, of which the following is a specification, reference being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in tables and relates more particularly to those which are adapted to be secured to chairs, beds or similar objects.

The primary object of the invention is to provide a table of this nature which shall be very simple in construction, cheap to manufacture and which, when not in use, may be disposed by the side of its support, so that it will not be in the way.

A. further object of the invention is to provide a table particularly adapted for use on arm chairs, and which may be vertically, angular-1y, or horizontally adjusted.

The invention also aims to generally improve devices of this nature and to render them more useful to students, invalids, doctors, etc.

WVith these and other objects in View, as will become more apparent as the description proceeds, the invention consists of certain novel features of construction, combination and arrangement of parts as I shall hereinafter fully describe and claim.

For a complete understanding of my invention, reference is to be had to the fol lowing description and accompanying drawings wherein I have shown my invention in use on an arm chair and whercin- Figure 1 is a side elevation of a chair showing my invention applied thereto, the dotted lines showing the position of the table when not in use. Fig. 2 is a front eleva tion. Fig. 3 is a side elevation of one of the arms which support the table, together with the attachments thereto. Fig. 4; is a longitudinal sectional view through one of the table arms and the connections there with. Figs. 5, 6, 7 and 8 are detail views of parts of my invention which will be hereinafter more fully described.

Similar parts will be referred to in the following description and designated in the accompanying drawings by like reference characters.

A designates an arm chair having the arms B and rockers C. To the under side of each of the arms B a longitudinally extending rod 1 is connected by means of suitable brackets 2. Telescoping rods 3 are pivotally connected at their lower ends to the rockers C and at their upper ends to the sleeve members 4, which are slidably mounted upon the rods 1 and which are formed with depending spaced cars 5 between which the upper reduced ends of the rods 3 are pivotally connected. Each of the sleeve members 4 is also provided with a set screw 6 whereby the members may be locked in any desired position.

A rectangular platform 7 forms the table proper and has secured to its under side, by any suitable means, a drawer S. A pair of angular brackets 9 is secured to the under side of the platform 7 adjacent each end thereof and supports the bars 10 and 11. Each of these bars is formed at its ends with the longitudinally projecting lugs 12 which project through central openings formed in the brackets 9 and the bar 10 is also provided intermediate its end with an apertured depending car 13 having one side thereof provided with the teeth l l. The bar 11 is formed interi'nediate its ends with a depending car 15 which is provided with the longitudinally extending end opening recess 16, the purpose of which will be hereinafter explained.

A doubly curved arm 17 having the sleeve member 18 formed upon one end thereof and provided at its other end with the hori' zontally projected portion 15) is slidably mounted upon one of the rods 3. The horizontally projecting portion 1!) of the arm 17 is rectangular in cross section for a portion of its length and has slidably mounted thereon the toothed disk 20. The extremity 21 of the arm 17 is of a reduced size, circular in cross section and adapted to project through the apcrturcd car 13. .An expansive spiral spring 23 holds the teeth of the disk 20 normally in engagement with the teeth 141; on the car 18. 2-1 designates a nut which is threaded upon the end 21 and which prevents the car 13 from becoming detached from the arm 17. From the foregoing description it will be seen that the normal engagement of the toothed disk 20 with the car 15 prevents the latter from turning about the circular portion of the arm 17 and the platform is therefore held against angular movement. To provide for the disengagement of the tion 19 of the arm 17. The inner end of the push rod 25 is provided with a transversely extending bar 26 which works within the slot 27. The toothed face of the disk 2Q, is provided with grooves for the reception of the cross bar 26 whereby the latter does not interfere with the meshing of the teeth upon the opposed faces of the disk and the ear 13. When it is desired to disengage the disk 20 from the ear 13, the rod 25 is forced inwardly causing the cross bar 26 to force the disk 20 inwardly against the spring 23. An arm 28 havin the sleeve member '29 formed on one end thereof is slid ably mounted upon the other of the rods 3 and is provided at its upper end with the outwardly projecting horizontal portion 30 upon the end of which a nut 31 may be threaded. The end portion 30 of the arm 28 engages the walls of the slot 16 formed in the car 15 and supports one end of the platform 7.

A book guard 32, clearly shown in Fig. 2, and having the laterally projecting portions 33 is secured to the inner side edge of the platform 7 and serves to hold a book thereon when the platform is tipped at an angle to the horizontal nlane.

It isthoiight that the foregoing descrip tion will suiiice to a clear understanding of the construction of my improved chair table, the operation of which is as follows :-To change the table from its operative position as shown in Fig. 2 to its inoperative position as shown by the dotted lines in Fig. 1, the end of the platform 7 which carries the bar 11 is swung upwardly whereby the other end of the platform assumes a pivotal movement about the transverse bar 10 and the under side of said platform is caused to engage the end of the push rod 25 thus releasing the disk 20 from engagement with the ear 13. The ear '13 is now free to rotate about the circular portion 21 of the arm 17 and the platform 7 is swung rearwardly and downwardly into a horizontal position parallel with the side of the chair. The set screw "34 which looks the arm 17 on one of the arms 3 is nextloosened and the arm 17 lowered to any desired position and then swung forwardly so as to bring the end portion 19 parallel to the side of the chair after which the set screw 34 is again tightened and the platform 7 swung inwardly against the chair. This last inward movement of the platform releases the push rod 25 whereby the disk 20 is forced outwardly into engagement with the toothed ear 18. When in use, the table may be turned at any angle to the horizontal plane and may be also moved toward or away from the occupant of the chair.

It is to re understood that while I have shown and described a preferred embodiment of my invention, I do not wish to be limited to this exact construction and arr-a-ngement of parts .but may make such changes as fall within the scope and spirit of the invention.
